How to work it out

  1. Divide the part by the whole: 66 ÷ 18 = 3.666667
  2. Multiply by 100: 3.666667 × 100 = 366.6667%
  3. Check: Work backwards: 366.6667% of 18 is 3.666667 × 18 = 66.

Another method. As a proportion of part to whole: 66/18 = p/100, so p = 66 × 100 ÷ 18 = 366.6667%. Both methods always give the same answer.

In a spreadsheet: =66/18*100. Dividing the wrong way round (whole ÷ part) gives a different answer. The number after “of” is always the whole, so it goes on the bottom.
